Along with some other equipment I acquired what I believe to be a
1950s, early 1960s TR switch.
I recognize the power supply it's attached to as a modified AMECO
unit. I can't remember the details of the unit in the foreground of
this picture which I believe is a TR switch. I also seem to remember
it being late 1950s to early 1960s vintage.
Take a look at:
Anybody with a better memory than mine?
Who made it? (Johnson???)
What does it do? ("isolate" the receiver from the antenna??? or??)
How does it fasten into the antenna system?
I probably won't ever use it but would like to know more about it
before I make that decision. If I know the years when it was sold I
can go to the library and try to find an ad or article in and old QST
